Introduction to Reductions & Sodium Borohydride (Theory & Problems)

The video tutorial covers the concepts of oxidation and reduction, focusing on the oxidation of alcohols and aldehydes to carboxylic acids. It explains the oxidation state hierarchy and introduces reagents for carbonyl reduction, specifically sodium borohydride and lithium aluminum hydride. Sodium borohydride is highlighted as a weak reducing agent effective on ketones and aldehydes, while lithium aluminum hydride is a strong reducing agent. Practical examples demonstrate the application of these reagents, emphasizing the conversion of carbonyl groups to alcohols.

What is the outcome of reducing a ketone with sodium borohydride?

Explain the reduction process of an aldehyde using sodium borohydride.

What happens when sodium borohydride is used on a carboxylic acid?

Discuss the limitations of sodium borohydride as a reducing agent.
